Question

I am trying to calculate pace (min/mi) and format it as mmmm:ss.

So far I calculate my pace into a float by taking 60 and dividing it by my average speed. At an average speed of 76mph, my average pace is displayed as 0.79. I want to format it so that it converts my 0.79 minutes to mmmm:ss (thus showing my average pace as 0000:47). How can I do this?

Answer 1

double milesPerHour = 76.0;
int secondsPerMile = (int)round(3600.0 / milesPerHour);
NSString *paceString = [NSString stringWithFormat:@"%04d:%02d", secondsPerMile / 60, secondsPerMile % 60];
